Eradication of invasive species: progress and emerging issues in the 21st century

At an international conference on the eradication of invasive species, held in 2001, Simberloff (2002) noted some past successes in eradication—from the global eradication of smallpox (Fenner et al. 1988) to the many successful eradications of populations (mostly mammals) from small islands (e.g. Veitch and Bell 1990; Burbidge and Morris 2002). However, he cautioned that we needed to be more ambitious and aim higher if we are to prevent and reverse the growing threat of the homogenization of global biodiversity. In this chapter we review how the management strategy of eradication—the permanent removal of entire discrete populations—has contributed to the stretch in goals advocated by Simberloff. We also discuss impediments to eradication success, and summarize how some of the lessons learnt during this process have contributed to the other strategies (prevention and sustained control) that are required to manage the wider threat posed by invasive alien species. We concentrate on terrestrial vertebrates and weeds (our areas of expertise), but touch on terrestrial invertebrates and marine and freshwater species in the discussion on emerging issues, to illustrate some of the different constraints these taxa and habitats impose on the feasibility of eradication.

Issues and advances in the integrated control of sheep lice.

Ongoing pressure to minimise costs of production, growing markets for low residue and organic wool and meat, resistance to chemicals in louse populations, and the deregistration of diazinon for dipping and jetting have contributed to a move away from routine annual application of lousicides to more integrated approaches to controlling lice. Advances including improved methods for monitoring and detection of lice, an expanded range of louse control products and the availability of a web-accessible suite of decision support tools for wool growers (LiceBossTM) will aid this transition. Possibilities for the future include an on-farm detection test and non-chemical control methods. The design and extension of well-constructed resistance management programs to preserve the effectiveness of recently available new product groups should be a priority.

Australian Property Institute Inc, Submission to the Productivity Commission on Intellectual Property Arrangements – Issues Paper

This submission responds to the document Intellectual Property Arrangements Issues Paper (Issues Paper) released by the Productivity Commission in October 2015 for public consultation and input by 30 November 2015. The API is grateful for the extension of time granted by the Commission to complete and lodge this submission. The overall need for an inquiry into intellectual property is supported by API. In particular it is noted with approval that the Commission states in its Issues Paper that it is to consider the appropriate balance between “incentives for innovation and investments, and the interests of both individuals and businesses in assessing products”.1 However, API is of the view that intellectual property in the area of real property presents a number of issues which are not fully canvassed in the abovementioned Issues Paper. Intellectual property embedded in valuation and other property-related reports of API members involves the acquisition of information which may possibly be confidential. Yet, when engaged in banks and financial institutions the intellectual property in such valuations and/ or reports is commonly required to be passed to the client bank or financial institution. In the Issues Paper it is proposed that there are seven different forms of intellectual property rights.2 It is the view of API that an eight form exists, namely private agreements. The Issues Paper, however, regards private agreements between firms as alternatives to intellectual property rights. The API considers that “secrecy or confidentiality arrangements”3 as identified in the Issues Paper form a much larger part of the manner in which intellectual property is maintained in Australia for the purposes of trade secrecy or more often, financial confidentiality...

DAQ00096 - Emerging Foliar Wheat Disease Issues in the Northern Region

The emerging disease program seeks to gain information on the distribution of cereal pathogens\pathotypes and potential for outbreaks across the norther region and options for their control. It is looking for an improved understanding of varietal (APR) reaction to stripe rust (YR) in prevailing weather conditions and in the face of climate change. Replicated field trials are used in the evaluation of varietal, cultural and chemical management of YR. Best management practice packages are disseminated to stake holders, including a YR predictive tool.

Implantable devices: issues and challenges

Ageing population and a multitude of neurological and cardiovascular illnesses that cannot be mitigated by medication alone have resulted in a significant growth in the number of patients that require implantable electronic devices. These range from sensors, gastric and cardiac pacemakers, cardioverter defibrillators, to deep brain, nerve, and bone stimulators. Long-term implants present specific engineering challenges, including low energy consumption and stable performance. Resorbable electronics may offer excellent short-term performance without the need for surgical removal. However, most electronic materials have poor bio- and cytocompatibility, resulting in immune reactions and infections. This paper reviews the current situation and highlights challenges for future advancements.

Issues of Digital Ecosystems Approach to Biological Ecosystem Simulation Model Fit Optimization

This study examines the application of digital ecosystems concepts to a biological ecosystem simulation problem. The problem involves the use of a digital ecosystem agent to optimize the accuracy of a second digital ecosystem agent, the biological ecosystem simulation. The study also incorporates social ecosystems, with a technological solution design subsystem communicating with a science subsystem and simulation software developer subsystem to determine key characteristics of the biological ecosystem simulation. The findings show similarities between the issues involved in digital ecosystem collaboration and those occurring when digital ecosystems interact with biological ecosystems. The results also suggest that even precise semantic descriptions and comprehensive ontologies may be insufficient to describe agents in enough detail for use within digital ecosystems, and a number of solutions to this problem are proposed.

Chickpeas! Varietal performance, wet feet and root rot, virus and salinity effects in 2012, Ascochyta management, seed quality, issues in central Queensland and effects of desiccating too early with glyphosate on seed germination

Take home messages: Plant only high quality seed that has been germ and vigour tested and treated with a registered seed dressing Avoid poorly drained paddocks and those with a history of lucerne, medics or chickpea Phytophthora root rot, PRR; do not grow Boundary if you even suspect a PRR risk Select best variety suited to soil type, farming system and disease risk Beware Ascochyta: follow recommendations for your variety and district Minimise risk of virus by retaining stubble, planting on time and at optimal rate, controlling weeds and ensuring adequate plant nutrition Test soil to determine risk of salinity and sodicity – do not plant chickpeas if ECe > 1.0-1.3 dS/m. Beware early desiccation of seed crops – know how to tell when 90-95% seeds are mature

Methodological issues with older users as research participants

Researching with older participants presents many unique methodological challenges. One of the reasons for this is the greater variability in abilities among older than among younger people. Thus, the standard practice in user research of assuming homogeneity in a certain demographic group may not work with older adults. Designing experiments for users with diverse capabilities is challenging and calls for re-examination of existing experimental design methods. In this paper we will share our experience in researching with people with diverse capabilities and present its implications and possible way to address them.

Issues and solutions for researching weed eradication target species

Species biology drives the frequency, duration and extent of survey and control activities in weed eradication programs. Researching the key biological characters can be difficult when plants occur at limited locations and are controlled immediately by field crews who are dedicated to preventing reproduction. Within the National Four Tropical Weeds Eradication Program and the former National Siam Weed Eradication Program, key information needed by the eradication teams has been obtained through a combination of field, glasshouse and laboratory studies without jeopardising the eradication objective. Information gained on seed longevity, age to reproductive maturity, dispersal and control options has been used to direct survey and control activities. Planned and opportunistic data collections will continue to provide biological information to refine eradication activities.

Assignments of non-retail commercial leases: Some contentious issues

Assignment clauses in non-retail commercial leases are as infinitely varied as the circumstances in which disputes arise. Each clause must be individually interpreted as part of the lease in which it is embedded. Whilst the assignment of a lease is one of the most commonplace transactions between lessor and lessee, the case law reveals few unifying principles. This article seeks to cautiously identify a set of principles which should be in the mind of any lawyer when a dispute relating to an assignment arises. It concludes with a short checklist of matters which must be considered by such a person to encourage the application of principles in the first instance towards a resolution of the dispute.

Directors and officers insurance – Recent critical issues in Australia and New Zealand

Directors and Officers Liability Insurance (“D&O insurance”) has grown and evolved rapidly over the past 80 years to assume an important position in most corporations’ corporate governance and risk management strategies. This article focuses upon certain topical matters of particular concern to directors and officers including the availability of defence costs where a D&O policy is subject to a statutory charge; the commercial desirability of stand-alone “A-side” coverage, being the cover provided directly to directors and officers for loss resulting from claims made against them for wrongful acts; the impact of fraud and/or dishonesty upon D&O cover; and disclosure of the nature and extent of D&O cover to the directors and officers themselves and to third parties – in the latter case such access frequently being necessary to determine the economic viability of pursuing a proposed action against a company and its directors and officers.
